Abstract
- Catalyst-loaded activated carbons are the widely used adsorbents to remove H<subscript>2</subscript>S for purification of the gas streams. Virgin carbon, single, and mixed catalyst-loaded carbon are used as adsorbents. Their performance of H<subscript>2</subscript>S catalytic conversion was studied by evaluating their breakthrough curves in order to investigate the effect of catalyst contents, categories, assistant catalysts, and virgin carbon properties on the H<subscript>2</subscript>S adsorption. The effects of gas stream properties on H<subscript>2</subscript>S catalytic adsorption are also investigated. The results show the H<subscript>2</subscript>S u amount is increased with catalyst contents, and the assistant catalysts can enhance H<subscript>2</subscript>S catalytic conversion. NaOH-loaded carbon has better catalytic performance than KOH-loaded carbon with the same contents. Carbons after impregnation keep a relative high-pore volume between 2 and 20 nm, which is beneficial to give full play to the catalysis. The relative humidity and oxygen can enhance the H<subscript>2</subscript>S adsorption capacity and play important roles in H<subscript>2</subscript>S adsorption. CTC has little effects on the impregnated carbon for H<subscript>2</subscript>S catalytic conversion. Carbon impregnated with a specific catalyst can accelerate target substance adsorption and will restrict the pore volume for organics adsorption. [ABSTRACT FROM AUTHOR]
